new: TRVHunSpell can use TNT Controls, if {$DEFINE USERVTNT} is activated in RVHunSpell.pas. Useful for old versions of Delphi (2007 and older).
This feature is impemented together with changes in TRichView and RichViewActions, allowing to make completely Unicode spelling check in non-Unicode versions of Delphi. New versions of TRichView and RichViewActions are available for registered users.

impr: in the spelling forms, the dialog font name is changed from 'MS Sans Serif' to 'Tahoma'.

- We corrected TRvDxSpellChecker for compatibility with newer version of Developer Express VCL components (DevExpress VCL v15.1.4 (v2015 vol 1.4) - Released on 27 Aug 2015). They dropped support of non-Unicode versions of Delphi and removed some functions supporting ANSI text

- We marked TRvDxSpellChecker and TRVHunSpell as 64-bit compatible components.

- We fixed a bug with "Change All" and "Ignore All" buttons for spell checkers that use our dialogs. This bug was caused by changed values of TModalResult ("yes to all" and "no to all" constants) since RAD Studio XE2.
